A brilliant cosmic burst 100 times as bright as our galaxy came from 2 black holes circling each other, study finds

Posted by in category: cosmology

The smaller black hole, with a mass of about 150 million suns, orbits its larger companion, with a mass of 18 billion suns, at near the speed of light.

It’s this rapid dance that sparked the bright flare from this system, according to a new study published in Monthly Notices of the Royal Astronomical Society in March.

The recorded burst, which astronomers observed in February 2022, occurred when the smaller black hole crashed into a disk of gas surrounding the larger black hole, the study’s scientists said.
